I like area + line charts for this. The area fill is the comp period and the line is the current. One of my favorite ways to do this (that most charting packages struggle with) is to use an area full for last year, a solid line for this year, and a dotted line for the future based on current trajectory. You can compare to multiple periods using stacked areas (particularly when you can assume previous periods had growth).
